1997 Nissan Altima P1320 Fault Code: Is It Caused by Ignition Coils?

Model: 97 Nissan Altima Fault Code: P1320 Posted: 2007-05-08 05:16

I recently received a P1320 diagnostic code on my 1997 Nissan Altima with a 2.4L engine and approximately 78,000 miles. After researching online forums, I've learned that ignition coils are often suspected as the root cause of this issue. I'm seeking confirmation from experienced users: is P1320 on a 1997 Nissan Altima typically related to faulty ignition coils? Additionally, I previously received helpful advice on my Daewoo vehicle, and I hope for similar support here.

The dealership can verify this issue — however, without physically inspecting the vehicle, their confirmation is limited.

While ignition coils are a common possibility, P1320 isn't always caused by them. It's important to first check the primary side of the ignition circuit (the 12V power feed to the coil) for shorts or opens. To do this, unplug the ignition coil and turn the key on with the engine off. Use a digital voltmeter (DVOM), not a test light, to verify if 12 volts are present at the connector. If battery voltage is detected, there's no open circuit or short in that section. The next step would be to swap the suspect coil with a known good one to confirm the issue.

There may be a technical service bulletin (TSB) available for this specific P1320 code on the 1997 Nissan Altima — worth checking with the manufacturer or dealership.
